Reset on any system reset. This register provides write access security when enabled by TZEN register bit in Section10: Reset and clock control (RCC). When security is enabled a non-secure write access will generate a bus error. Secure and non-secure read accesses are granted and return the register value.

See individual bits for reset condition. Access 6 wait states when writing this register. This register provides Write access security when enabled by TZEN register bit in Section10: Reset and clock control (RCC). When security is enabled a non-secure write access will generate a bus error. Secure and non-secure read accesses are granted and return the register value. When a system reset occurs during the register write cycle the written data is not guaranteed.

Not reset by wakeup from Standby mode, but by any application reset (NRST, IWDG, ...). Access 6 wait states when writing this register (when clearing a WKUPF, the AHB write access will complete after the WKUPF has cleared). This register provides Write access security when enabled by TZEN register bit in Section10: Reset and clock control (RCC). When security is enabled a non-secure write access on individual WKUPC[6:1], WKUPP[6:1] bits and WKUPPUPD[6:1] bit pairs will be discarded when the corresponding WKUPEN[6:1] bit in PWR MPU wakeup enable register (PWR_MPUWKUPENR) is set. No bus error will be generated. Secure and non-secure read accesses are granted and return the register value. When a system reset occurs during the register write cycle the written data is not guaranteed.

Not reset by wakeup from Standby mode, Application reset (NRST, IWDG, ...) and VDD POR, but reset only by VSW POR and VSWRST. Access 6 wait states when writing this register. After reset the register is write-protected and the DBP bit in the PWR control register 1 (PWR_CR1) has to be set before it can be written. When DBP is cleared, there will be no bus errors generated when writing this register. This register shall not be accessed when the RCC VSWRST register bit in Section10.7.89: RCC Backup Domain Control Register (RCC_BDCR) resets the VSW domain. This register provides Write access security when enabled by TZEN register bit in Section10.7.2: RCC TrustZone Control Register (RCC_TZCR). When security is enabled a non-secure write access will generate a bus error. Secure and non-secure read accesses are granted and return the register value. When a system reset occurs during the register write cycle the written data is not guaranteed.
